SPECIFICATION forming part of Letters Patent No. 676,355, dated. J une 1 1, `1901.

Application filed January l2, 1901. Serial No. 43,053. (No model.)

Io and is more especially an improvement upon the device shown and described in Patent No. 292,420, granted to me on January 22, 1884. Its primary object is to provide a device of this character which is adapted to be set up 15 for the construction of cisterns of different sizes and which after the cement `or other material placed therearou'nd is hardened can be taken apart and readily removed through the neck of the cistern. A further object is to provide means o novel construction whereby the cistern may be adjusted vertically to a desired height.

Another object is tovprovide staves which form the side walls of the curb and which are detachably secured in a novel manner to the frame of the curb.

Vith these and other objects in view the invention consists in providingr acurb-frame which comprises, preferably, three similar 3o rings formed in sections, which are adapted the frame, and means are provided whereby these uprights may support'said middle ring. A standard is arranged at the center of the curb, and braces extend therefrom and engage the rings, serving to prevent the same 4o from moving inward toward the center. Ribs are arranged upon the upper ring, and the inner ends vthereof are supported upon a jointed ring having standards which are adapted to bear upon a block arranged at the These ribs form the dome of the curb and any suitable number may be employed. The inner ends of the ribs support a preferably metallic strip, which is adapted to be bent into cylindrical 5o form and the adjacent ends thereof secured together. A jacket of suitable construction is adapted to be arranged without this cylinder and to inclose the saine, leaving sufficient space therebetween to form the neckof the cistern when cement, concret-e, or other material is placed therein.

The invention also consists in the further `novel construction and combination of parts `hereinafter more fully described and claimed, `and illustrated in the accompanying drawings, showing the preferred form of my invention, and in which Figure l is a vertical transverse section through the cistern, showing the curb in position therein. Fig. 2 is a top plan view of the dome of the curb. Fig. 3 is a section on line n; of Fig. l. Fig. 4 is a detail view of `one ofthe sections of the curb, showing the ring-sections, the standards thereof, and the staves secured to said ring-sections. Fig. 5 is a section on line y y of Fig. l. Fig. 6 is a perspective View ot' the dome-support, and Fig. 7 is a plan and 'elevation of the base of said support.

In constructing a cistern by employing a curb forming the subject-matter of this application the bottom of the hole within which the cistern is to be located is covered with a concave layerof ce ment or concrete of desired thickness, as shown atl in Fig. 1. Wedges 2 are then arranged at suitable intervals around the edges of the base l, and a ring 3, formed, preferably,of four similar sections, is placed thereon, the ends of said sections being held together by means of straps 3a, which are adapted to engage staples 4 and to be se= cured thereto by means of hooks 5, pivoted upon the straps. Each of the sections of this lower ring is, as shown in the drawings, formed of'two layers or thicknesses of wood or other material, the upper thickness being of less width than the lower thickness, thereby forming a recess 6 at the outer edge of the ring, which is for the purpose hereinafter more fully described. Blocks 7 are arranged upon the base l at the center thereof and serve to `support a standard 8, which extends upward IOC' prevent lateral movement of the braces. Plates 12 are secured to the outer ends of the braces 9 and extend therefrom, and these plates are adapted to extend over the inner edge of the ring 3, and thereby retain the braces in thelposition shown in Figs. 1 and 3.

Standards or strips 13 are then placed in av vertical position upon the ring 3 at regular intervals. Each of these supports comprises two similar strips having perforations 14 therein at desired intervals. Any one of these perforations in each strip is adapted to receive a pin 15, which extends transversely through the strips and holds them in proper relation to each other. to be placed within apertures 16, formed within a second ring 17, which is similar to the ring 3, before described, and is, like said ring, formed of preferably four sections secured together by means of straps, hooks, and staples. It will be seen that when the sections of the ring 17 have been lowered a suflcient distance they will contact with the'pins 15 in the supports and be held in position at the desired distance above the ring 3. A hoop 18 is secured to the periphery of the ring 17 and extends upward from the upper face thereof. This hoop is secured to the ring in any suitable manner, as by means of nails or screws, and is formed in sections equal in number and size to the sections of the ring. Blocks 19 are arranged upon the sides of the central standard 8 at points in horizontal alinement with the ring 17, and these blocks serve to supportkbraces 9, similar to those before described, and which also engage feathers 1l, projecting from the face of the standard. The upper ends of the strips 13 contact with and support a -third ring 20, which is formed of sections secured together and which is otherwise similar to the rings 17 and 3'before described. Braces 9 are provided for this ring, and the inner ends thereof are secured to the central standard 8 in the same manner as are the braces before referred to. Apreferably circular block 2l, such as shown in Fig. 7, is provided with an aperture 22 at thecenter thereof for the reception of the upper end of the central standard 8, and this block is adapted to lie upon the inner ends of the upper braces 9, rotary movement thereof being prevented by the feathers 11 at the upper end of the standard and said feathers lying within recesses 23, formed within the vss walls of the aperture 22. Vedges 24 are arranged upon the upper face of this block and at rightangles to each other, the reduced ends thereof being removed from each other. After the rings have been placed in the positions herein described staves 25 of the proper height are placed with their lower ends within the recess 6, formed at the upper edge of the lower ring 3. Each of these staves isprovided at the center with a downwardly-extending hook 26, which is adapted to engage the upper edge of the hoop 18, before referred to, when the staves are in position withinl These supports are adapted- .referred to.

the recess G. These hooks will, as is obvious', hold the staves in an upright position and prevent the same from being removed until after they have been disengaged from the hoop. The sides of the staves are beveled inwardly and toward each other, one of them, however, 27, being beveled in the opposite direction. This last-named stave is adapted to be placed in position after the remaining staves have been secured to the hoop. After the staves have been all placed in the position the concrete or cement to form the Walls of the cistern is packed between the earthen wall and the staves. The frame of the dome of the cistern is then placed in position. This frame comprises ribs 28, which are arranged in pairs, the ribs of each pair being connected by means of strips or slats 29. The outer or lower ends of the ribs are beveled and bear upon the upper ring 20, before the ribs are supported by a ring 30 (shown in Fig. 6) and comprise two similar sections hinged together and provided with standards 31, which are hinged to the lower surface thereof at regular intervals. These standards are adapted to rest upon the wedges 24 on the block 21, and it will be understood that when theyare slid upon said wedges the ring will be forced upward, thereby firmly binding the sections of the dome together. These sections 29-of the dome are also provided with edges which are beveled inwardly and toward each other, one of them, however, being beveled in the opposite direction and being adapted to be placed in position last and removed first. After the dome has been constructed as herein described cement or concrete is placed thereover, and, if de sired, asection of pipe 32 may be placed therein, as shown in Eig. 1. When the frame of the dome has been completely covered, a strip of preferably sheet metal is bent into cylindrical form and placed upon the inner ends of the ribs 28. The adjacent ends of this strip 33 are secured together by means of a hook 34 or in any other suitable manner. A jacket, comprising vertical ribs 35, secured to the bands 3G, is then placed outside of the strip 33, with its lower edge bearing upon the cement of the dome. The space between this jacket and the strip 33 is then filled in with cement or concrete and the construction ofthe cistern is completed. The curb isleft in position until the 'cistern is hardened, and the parts are then removed by reversing the operation hereinbefore described. l I

It will be seen that the strip 33 can be readily removed by unlocking the hooks 34 and springing the adjacent ends of the strips over each other. This will obviously decrease the diameter of the cylinder and the same may then be vreadily removed from the neck. The jacket being located outside of the neck can, as is obvious, be removed in any suitable manner. The standards or supports 3l are knocked olf of the wedges 24, causing the ring 30 to drop, and said ring isfolded upon itself and can be drawn out through the neck. The other parts can then be removed after the same have been detached from each other.

I preferably provide pins 37 upon the wedges, so as to prevent the supports or standards 3l from slipping downward upon the inclined faces of the wedges. These pins can be removed when desired. Each of the rings I also provide, preferably, with a wedge 38, which is adapted to lie between the adjacent ends of two of the sections. A strip 39, of metal or other material, is pivoted upon each of these wedges and is adapted to overlap the edges of the sections of the rings, thereby retaining the wedges in position. W'hen it is desired to remove the rings, these wedges are first removed after the braces 9 have been disengaged from the stationary rings. As soon as these wedges are taken out the sections of the rings will be loosened and can be readily detached.

After the parts of the curb have been removed the bottom walls and neck of the cistern shouldbe gone over with cement and all the rough parts `thereof filled in.

It will of course be understood that when it is desired to adjust the frame of the curb to'cisterns ofgreater'height it is necessary to employ a larger standard 8 and longer staves 25. The supporting-strips 13, however, can be adjusted by sliding the sections thereof upon each other and placing the pins l5 in engagement with desired apertures 14.

In the foregoing description I have shown the preferred form of my invention; but I do not limit myself thereto, as I am aware that modications may be made therein without departing from the spirit or sacrificing the advantages thereof, and I therefore reserve the right to make all such changes in the details of construction as may properly fall within the scope of my invention.
